A successful public transportation system is an essential component of a liveable, smart, and sustainable city, but what are the barriers to improved performance of Phnom Penh’s City Bus programme? The purpose of this paper is to elucidate factors influencing bus-riding behaviour and suggest policy and planning actions that could increase ridership. Using the Theory of Planned Behaviour (TPB) as an overarching guide and structural equation modelling (SEM) as the primary method of analysis, we explored ridership perceptions of 324 university students in Phnom Penh. We focused on this segment of the city’s population as they are highly mobile, tend to be sustainability- conscious, and are predisposed to non-physical, digital, planning strategies. The SEM results indicated that the factors of timeliness and general safety and comfort onboard are significant predictors of attitudes towards bus ridership. Beyond service attributes, a broader SEM analysis of behavioural intentions suggested that subjective norms (perceived social pressure from important referents), personal norms (self-based moral obligation), and positive anticipated emotion (prospects of affective response to performance of behaviour) are significant factors in predicting bus-riding behaviour among university students. Using the results of the SEM analysis, both physical (e.g., bus priority lanes, enhanced walkways and bus stops) and non-physical, information technology alternatives are suggested to enhance bus ridership.\u0000\u0000\u0000","PeriodicalId":428713,"journal":{"name":"Journal of Architectural/Planning Research and Studies (JARS)","volume":"62 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131042354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exploring the possibility of using an EAC in an indoor area, this research aims to determine its benefits in a natural, ventilated room during summer and winter. In terms of human thermal comfort, these benefits are evaluated through the CBE Thermal Comfort Tool with environmental parameters collected from the testing room. Bacterial growth due to increased humidity is analyzed based on bacterial counts in the opened Petri dishes. The results from the testing room with EAC show that air temperature reduces by 1.4 - 4.4 °C during winter and 3.3 - 3.5 °C during summer with a relative humidity increase of 2.3 - 13.1%. Thermal comfort was found to depend on indoor air temperature and air velocity. During winter, it was slightly improved by the use of an EAC, with an elevated percentage of people dissatisfied (PPD) due to low air temperature and high air velocity. The evaporative, cooled air also enhances thermal comfort in summer with less PPD. Increasing air velocity to provide thermal comfort is more suitable in summer than in winter. More bacteriological colonies formed in the room with an EAC than in the room with natural air by 33-55 units. The air quality in the EAC room according to IMA standards was Fair-Good, dropped from Good-Very Good in the natural-air room. This study confirms that the EAC improved thermal comfort in the natural ventilation room during both summer and winter. However, the room air was impure with the increase in microbial activity due to high air temperature and humidity.\u0000\u0000\u0000","PeriodicalId":428713,"journal":{"name":"Journal of Architectural/Planning Research and Studies (JARS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126530321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new BRT system, which costs much less than a subway or a light rail system, has brought transportation in Curitiba a new dimension. All stations look and feel like train stations and are accessible to the disabled. He also turned floodplains into public parks and made Curitiba among the world’s most per-capita park area. These projects have improved the quality of life of people as well as save millions of budget to the city of Curitiba.","PeriodicalId":428713,"journal":{"name":"Journal of Architectural/Planning Research and Studies (JARS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128009716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the qualitative approach were used to develop the questionnaires which were conducted with 18 experts/ planners and 111 selected stakeholders. The findings indicated that the interest, influence, and area-based were the key attributes used by planning agency/planners to select the stakeholders to participate in the participatory planning processes. On the other hand, the selected stakeholders relied on the interest, area-based, influence, and urgency to decide to participate in the participatory planning process of Khon Kaen Smart City. Furthermore, the selected stakeholders preferred the on-place-participation rather than e-participation and informal and indirect participation gateways to have an influence on the processes of decision-making.
